This bespoke design option provides the opportunity to view the inner watch movement through the watch case back, by removing the flat centre of the stainless steel caseback and replacing it with a clear sapphire crystal.

The crystal is then etched using a subtle ghosting effect with the PROJECT X DESIGNS, X logo and then sealed using the same techniques + resins currently used by the all of the leading swiss watch manufacturers, to ensure that the watch retains its water proofing capabilities.

DLC Black coating to - Movement Rotor can also be added for a contrasting effect, and then the movement engravings enamelled (as displayed in the photograph provided).

A very cool and interesting look.

but the caseback could be replaced if required at a later date.

PLEASE NOTE: The addition of a sapphire crystal caseback does NOT affect the waterproofing of the watch or function of the movement in ANY way

The process NOT reversible,
